Thank you, and under system services you also have all these system services toggled on? (Screenshot attached below)

Do you personally have significant locations turned on? apparently optimized battery charging does not work unless that is turned onHere’s a page that breaks down what they all do. I only enable the ones I am actually using, but that’s just me.
How to adjust location access for the system services on iPhone and iPad
If the iPhone location privacy matters to you, learn how to toggle GPS location access for iOS's system services on the iPhone and iPad.
Out of curiosity, why did you opt to disable Cell Network Search?
It doesn’t help the functionality in anyway and only contributes to the battery drain.
I have but rarely need to. I charge it when it gets to 40% and it stops it a 80%. That easily lasts me a day. I have around 49 charge cycles on my 15PM purchased a day after it was released.
Thats amazing. What system services do you have enabled under Settings > Privacy and Security > Location Services > System Services? do you have all the toggles turned on and enabled or did you switch any of them off?
Not really. I'm not what you would call a heavy user. When I'm home I usually use my 12.9 M1 iPad Pro for everything so that pretty much does all my heavy lifting. System services settings:
I have one more question, whats the reason you turned off Networking and Wireless? that seems like an essential system service to keep enabled
I turn things off and see how it effects my day to day use. Turning off Networking and Wireless doesn't seem to effect anything in a negative way as far as I can tell.. It's difficult to find information on what exactly each category actually does and why it needs to be enabled.. All I know is the Phone operates normally and does everything I expect it to do
Based on my research turning that Networking and wireless toggle turns off the U1/U2 chip in the iPhone. Not sure what negative/positive effect that has on the phone’s performance
Do You mean the U1/U2 ultrawide-band chip? I haven't had any issues locating my Airtags using the precise location tracking or with Airdrop. I haven't tried NameDrop so not sure if that works properly. If that's the case I would turn it on just so all that functionality works as intended.. Where did you find the info on what Networking and Wireless actually controls?
Yes I meant U1/U2 chips. This video explains each of the services one by one and says the Ultrawideband chip is turned off by switching that toggle:
The only two system location services I have on are Setting Time Zone and System Customization so that Night Shift turns on automatically at sunset wherever I am. Maps routing (I take public transit) works just fine.
And no, I don’t use Clean Energy Charging—just the 80% charge limit on my 15.
How is your battery life overall with system services set up that way? You do realize compass calibration is essential for all map apps to function properly? Not sure why you turned that off. Motion calibration and distance is another very important one. Significant locations is required for optimized battery charging to workThe only two system location services I have on are Setting Time Zone and System Customization so that Night Shift turns on automatically at sunset wherever I am.

And yeah, I don’t use Find My or AirTags at all, either.
Quite good on a base iPhone 15. Would probably be better if I didn’t have the Weather widget on my home screen, but alas—that is one place I sacrifice some (slight) efficiency for convenience. I do not, however, grant Weather—or any app, for that matter—to “Always” access my location.
Because I don’t need it or Motion Calibration & Distance to ride the bus to and from work on my usual day. I’ll maybe turn those on, along with Satellite Connection, if I’m getting lost walking somewhere tricky around highway overpasses or something unusual.
Apple says significant locations is required to be on for optimized charging to work. See the screenshot below.Because I don’t need it or Motion Calibration & Distance to ride the bus to and from work on my usual day.

Compass Calibration and Motion Calibration & Distance are also constantly pinging one’s location so I find leaving them on extra unappealing.
And no, Significant Locations is not necessary for the 80% charge limit to work.
